Mamta A. Satoor commented on DERBY-5051:
----------------------------------------

Kim, thanks so much for working on this. The changes look great. I just had one question.
I didn't see any mention of the following optional properties in derby.log
derby.stream.error.file
derby.stream.error.method 
derby.stream.error.field 

Maybe you documented it and I missed it. Thanks

> With DERBY-4853, we log additional information in derby.log to make it easier for the
support group to work with customer problems.
> Following 2 additional properties will now always be put in derby.log (every time a database
is booted) 
> user.dir 
> derby.system.home 
> user.dir is the system property which gives the user working directory. 
> If the user has not specified derby,system.home, then Derby will look for optional derby.properties
file in user.dir . If user has provided derby.system.home, then the optional derby.properties
will be looked in derby.system.home rather than user.dir 
> If user has not provided derby.system.home, then a sample of the 2 properties on derby.log
looks as follows on my machine 
> user.dir=C:\p4clients\svnmain\client2\trunk\systest\out142 
> derby.system.home=null 
> If user has set derby.system.home to c:./temp, then a sample of the 2 properties on derby.log
looks as follows on my machine 
> user.dir=C:\p4clients\svnmain\client2\trunk\systest\out142 
> derby.system.home=c:/temp 
> In addition to the above 2 properties, there can be following 3 optional properties in
the log (following the 2 properties mentioned above) 
> derby.stream.error.file 
> derby.stream.error.method 
> derby.stream.error.field 
> The above 3 properties provide a way to alter where error messages get logged rather
than tranditional derby.log file. In the absence of the above 3 optional properties, the location
of derby.log follows the same logic as derby.properties. But if the user has set any or all
of the 3 optional properties, then derby.log will not be in same location as derby.properties.
In the Derby code, derby.stream.error.file takes precedence over the other 2 properties and
derby.stream.error.method take precedence over the last property.
